KNITTING-VIACHINE.

SPECIFICATION forming part of` Letters Patent N o. 669,730, dated March 12, 1901.

Eipplioation filed November 3, 1898. Serial No. 695,394. (No model.)

o cir/ZZ whom t may concern.-

Be it known that LEDWARD E. KILBOURN, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of NeT Jersey, have invented certain new and useful Improvements in Knitting- Machines; and Ido hereby declare the following to `be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

My present invention relates to the art of knitting, and has for its object the improvement of circular-knitting machines, more especially the class of such machines that is employed in knitting seamless hose. In the manufacture of such hose it is often desirable to throwin a strengthening-thread on the back of the leg, above the heel, and also in the same or other hose to throw a strengtheningthread in the bottom of the foot. The devices which in part constitute my present invention are designed to effect these two results, either together in the same stocking or separately in dil'erent stockings.. I have in this instance shown my present improvement as adapted to and connected with the circular-knitting machine which forms the subject of my former application for patent tiled May 4, 1896, and given Serial No. 590,218, though it will of course be understood that the principle of m-y invention may be applied to any other knitting-machine with which it can be operated.

In the accompanying drawings I have illustrated the best form in which I have contemplated' embodying my in ventiou to operatively combine the same with the character of knitting-machine heretofore referred to, and my said invention is disclosed in the following description and claims.

In the drawings which are filed herewith and form a part of this application, Figure l with my present invention attached. Figs. 2 and 2, taken together,give a view in front elevation of my said machine. Figs. 3 and 3, taken together, give a View in rear elevation. Figs. 4 and 4a, taken together, give a plan View of the mechanism below the bedplate of the machine. Fig. 5 is a view of the mechanism adjacent to the right-hand end of the machine. Fig. 6 is a view in elevation of mechanism adjacent to the left-hand end of the machine. Fig. 7 is a plan view Iof mechanism below line or fr, Fig. 3a. Figs. 8, 9, l0, 11, 12, and 13 are views of details and detached portions of the mechanism shown in Fig. 7. Fig. 14 is a plan of mechanism near the right-hand end of the machine, parts of the mechanism immediately beneath. the bedplate being removed. Figs. 15, 16, and 17are details of parts of the devices which change or vary the stitch. Fig. 18 is a top or plan View of the needle-cylinder and connected devices with the bobbin-holders removed and with the releasers for the reciprocating threadguide driver in one position, and Fig. 19 is a like top plan view with the reieasers in another position. Fig. 20 is a sectional view of the extension of the cam-cylinder-driving shaft. Fig. 2l is a plan of the gearing on the thread-guide-supporting arm. Fig.. 22 is a detail of the devices connecting the gearing on the arm and the shaft extension. Fig. 23 is an elevation of the upper end of the eXtension of the cam-cylinder-driving shaft with the thread-controlling devices, a part being broken away. Fig. 24 is a vertical sectional view of the main part of the construction shown in Fig. 23. Fig. 25 is a section taken ou line 3 3, Fig. 26 is a section on line 4 4, Fig. 27 is a section on line 2 2, and Fig. 23 is a section on line l l, all of which lines are to be found in Fig. 24. Fig. 29 is a side elevation of the devices which control the splicer cam-ring. Figs. 30 and 3l are top views of the same. Figs. 32 and 33 are two views, one at right angles to the other, showing the cam which serves to actuate the devices which control the splicer cam-ring. Fig. 34 is a development of lower cam-cylinder in a straight line, and Figs. and 36 are views of one of the releasers for the reciprocating threadguide driver in two different positions.

In most particulars the main operative parts of the machine shown in the figures of the drawings just described are like those shown and described in my former application, Serial No. 590,218, hereinbefore referred to.

In the drawings, l is the bed-plate of the IOO
